The particle-in-cell method
WebbABSTRACT: In work, it is constructed a discrete mathematical model of motion of a perfect fluid. The fluid is represented as an ensemble of identical so-called liquid particles, which are in the form of extended geometrical objects: circles and spheres for two-dimensional and three-dimensional cases, respectively. WebbFinally, we cover the Boris method for integrating particle velocities in the presence of a magnetic field and simulate a magnetic mirror. Lesson 5 (3D Flow past a Sphere): In this lecture we start developing a three-dimensional Cartesian (XYZ) code for modeling flow of plasma past a sphere at a fixed potential.
